新型芳基取代5,6-去甲斑蝥酰亚胺衍生物的质谱研究(英文)

Mass Spectra of Novel 5,6-Dehydronorcantharidin Derivatives Substituted by Aromatic Amine

旨在研究一系列5,6-去甲斑蝥酰亚胺衍生物的质谱裂解特征。研究结果显示异(口恶)唑并N-取代去甲去氢斑蝥酰亚胺衍生物,即各种1,3-偶极子氧化腈"现场"与N-取代斑蝥酰亚胺进行[3+2]环加成的系列产物在电子轰击下,质谱裂解的各种碎片呈现了此系列杂环分子结构环消除的规律性-逆1,3-偶极环加成反应的历程。

The mass spectra of a series of novel 5,6 - dehydronorcantharidin derivatives substituted by aromatic amine have been examined. The paper is to report the preliminary results of an investigation of the mass spectrometric behavior of heterocyclic compounds formed by l, 3 - dipolar cycloaddition reaction of nitrile oxides and N - substituted canthaldinimides which is formed by Diels- Alder reaction to show that such compounds upon electron impact may fragment by way of a cyclo- elimination reaction corresponding, formally, to the reverse process of their formation.
